Opportunities and Challenges of High-field and Ultra-high-field Magnetic Resonance Imaging in China

doi:10.11938/cjmr20243142

Abstract

Abstract:

Magnetic resonance imaging (MRI), as a non-invasive, high-resolution medical imaging technology, is a powerful tool for clinical disease diagnosis. Current MRI systems are advancing towards higher magnetic field strength. High-field (HF) and ultra-high-field (UHF) MRI have demonstrated substantial advantages in clinical diagnosis and emerging cutting-edge imaging technologies, making them a focus of global competition. HF and UHF MRI equipment serves as a fundamental guarantee for scientific research and clinical applications, and is emphasized and supported as a strategic industry in many countries. This paper comprehensively analyzes the global market landscape and core technology competition in HF and UHF MRI equipment, highlights opportunities and challenges for China’s development in this field, and proposes targeted recommendations.

Key words: magnetic resonance imaging (MRI), ultra-high-field, AI, magnets
